Khloe, 37, and Tristan broke up in 2019 after three years of dating when multiple cheating rumors arose. They got back together in 2020 during the COVID-19 pandemic before calling it quits again in June 2021.

During their meet-up, the momager admitted she had been personally hurt over the athlete's disrespectful actions.
"When you hurt her, you hurt me, you hurt all of us," Kris replied. "The bottom line is we just want her to be happy, and we want you to be happy, and we want you to be happy as a family."
"I still think he's a great guy and a great dad," Khloe said during ABC News Special on April 6, "he's just not the guy for me."
